7.1.2
Figure 7.2 shows an example of an external connection in which a 32.768 kHz oscillator is used as the clock
source.
The 32.768 kHz oscillator and oscillator circuit is connected to the OSCI and OSCO pins as shown in Figure 7.2.
The CLKSEL pin should be set to Low level.
The OSCEN pin should be set to High level.
The CLKI pin should be set to Low level.
Table 7.1 gives typical external circuit constants for a 32.768 kHz oscillator. These will vary, depending on
individual oscillator characteristics (e.g., components and circuit board patterns used). The values given in Table
7.1 are examples only and do not constitute performance guarantees.
